Reminds me of me and a long time sub cock sucker i know. He loves to be in a mask and collar I taught him how to give me a custom blowjob the way I like. When I cum its bliss.
One of the best things about a nice long edging blowjob like this is that you get to hold his cock in your mouth a lot longer....but the best thing is the growing anticipation of that glorious pulsating orgasm that fills your mouth with cum at the end.
